power: supply: 88pm860x_battery: fix the return value handle for platform_get_irq()

There is no possible for platform_get_irq() to return 0,
and the return value of platform_get_irq() is more sensible
to show the error reason.

Change 'long long int' to 'long long' because the int is unnecessary,
as suggested by checkpatch.pl.

power: supply: check if calc_soc succeeded in pm860x_init_battery

clang static analysis flags this error

88pm860x_battery.c:522:19: warning: Assigned value is
garbage or undefined [core.uninitialized.Assign]
info->start_soc = soc;
^ ~~~
soc is set by calling calc_soc.
But calc_soc can return without setting soc.

So check the return status and bail similarly to other
checks in pm860x_init_battery and initialize soc to
silence the warning.

power: supply: 88pm860x_battery: remove redundant dev_err message

In the pm860x_battery_probe(), when get irq failed, the function
platform_get_irq() logs an dev_err message, so remove redundant
message here.

power: move power supply drivers to power/supply

This moves all power supply drivers from drivers/power/
to drivers/power/supply/. The intention is a cleaner
source tree, since drivers/power/ also contains frameworks
unrelated to power supply, like adaptive voltage scaling.
